Frequently Asked Questions
Q: Is GWK-PTH50-CK-N interchangeable with GWK-PTH50-CK?
A: Yes. GWK-PTH50-CK-N is equivalent to GWK-PTH50-CK and 310701-121-KIT. The difference is that GWK-PTH50-CK-N uses 95A durometer steer wheels, which are slightly softer than standard wheels. Both kits fit the same mounting points on Crown PTH50 pallet jacks (serial 7-000000 and higher). Use GWK-PTH50-CK-N if softer steer wheels are needed for sensitive flooring or slow-speed precision work.
Q: What is the difference between 70D load wheels and 95A steer wheels in GWK-PTH50-CK-N?
A: GWK-PTH50-CK-N uses 70D ultra-polyurethane for the load (front and rear) wheels and 95A polyurethane for the steer (side) wheels. The 95A steer wheels are softer and provide better grip and floor protection for turning and directional control. The 70D load wheels are harder to resist compression under the rated 5000 lb load. This combination optimizes steering control while maintaining load capacity and durability.
Q: What is the compatibility serial range for GWK-PTH50-CK-N?
A: GWK-PTH50-CK-N fits Crown PTH50 pallet jacks with serial number 7-000000 and higher. Do not install on machines below serial 7-000000 because wheel bore and axle geometry differ. If your PTH50 nameplate shows a serial below 7-000000, contact your supplier for an alternative kit designed for earlier production models.
Q: Why would I choose 95A steer wheels instead of standard 70D steer wheels?
A: Choose GWK-PTH50-CK-N if you operate on polished concrete, tile, or other smooth surfaces where steering precision and floor protection are priorities. The 95A steer wheels grip better and reduce scuffing marks. In high-volume rough concrete environments, standard 70D wheels are harder wearing. If your facility has mixed flooring, GWK-PTH50-CK-N provides a balanced solution because the 70D load wheels remain durable under constant load.
Q: How do I identify which Crown part I have installed: GWK-PTH50-CK or GWK-PTH50-CK-N?
A: Physical inspection: 95A steer wheels (GWK-PTH50-CK-N) are visibly softer and compress slightly when squeezed by hand compared to 70D standard wheels. Check the wheel markings: look for durometer ratings printed or molded on the wheel sidewall. Review your parts invoice or work order to confirm the kit model number. If unsure, measure the load wheel durometer (should be 70D in both kits) to confirm the kit is correct.
Q: Do GWK-PTH50-CK-N wheels have sealed bearings?
A: Yes. GWK-PTH50-CK-N includes precision-sealed roller bearings in both load and steer wheel assemblies. Sealed bearings are pre-lubricated with synthetic oil and require no maintenance greasing. The seals protect the bearings from moisture and dirt common in warehouse environments. Do not attempt to open sealed bearings. Replace the wheel assembly if bearing noise develops or bearing play is detected.
